The Night Fision PLATE+NS 507K is a machined optic mounting plate and backup iron sight system purpose-built for the Glock 43X and 48 MOS platforms. This combo pairs a precision-engineered mounting plate with a lower third co-witness backup sight setup, giving your compact carry gun a bulletproof optics solution that works in any light. Whether you're setting up a duty gun, a defensive carry piece, or running drills at the range, this system lets you go from red dot to irons instantly without fumbling or second-guessing your sight picture.

The optic plate itself is machined from 17-4 stainless steel and nitride coated to withstand the abuse of duty carry and frequent shooting. It's engineered to interface with the Holosun 507K and other compatible optics, and at .08" thick, it provides a rock-solid foundation for your glass. The included backup sight package features a tritium-illuminated front sight paired with a blank rear sight, both set up for lower third co-witness. That means your optic stays centered in your view while your irons stay visible and functional as a true backup, not just a backup backup.

The tritium front sight glows without batteries or activation, giving you a visible reference point in darkness or dim indoor spaces—exactly what matters when speed counts. The rear sight blank is serrated to kill glare and keep your focus on the front sight and target. Night Fision includes extra screws and an installation tool, so you're ready to mount and go. This is a no-compromise setup for shooters who refuse to sacrifice iron sight redundancy just because they run a red dot.
